T 0 all whom it may concern:

Be it known that I, KARL FINKENZELLER, a subject of the Grand Duke ofBaden, residing at Freiburg, Baden, Germany, have invented certain newand useful Improvements in Fodder Purifying and Preparing Machines, ofwhich the following is a specifieation.

My invention. relates to an improved apparatus for preparing fodder andremoving dust from the same.

Good fodder must be free from dust, mold, fungi, and the like, and alsomust be fed to the cattle in a somewhat open and not compressedcondition in order to be nutritious and appetizing.

By the present invention, the fodder is subjected by means of anautomatic machine to such treatment that fodder originally possessingvery undesirable qualities is delivered from the machine in anappetizing and immediately utilizable form. This is efiected firstly bytearing open the parts of the fodder and subsequently throwing them outduring which the dust and other impurities are removed by the aid of afan, while the hay flowers and other particles of nutriment, even smallones, are left behind in the fodder and the nutritive value thereof istherefore not diminished although in quality a higher value is attained.By means of the opening up and rendering loose of the particles of thefodder, the appetite of the cattle is encouraged and the animals candigest it better. A further means for increasing the flavor of thefodder consists in irrigating with salt water or other appetizingingredients which can be added to the prepared fodder as it comes out ofthe machine.

The preparation of the fodder is effected in three operations so thatthere is no violent treatment which would destroy the filaments. Firstlywith the aid of auxiliary devices in the supply hopper the fodder isconducted to a toothed drum which draws it around, opens it up by theaid of counterteeth separating each particle of fodder from the otherand delivers it over an adjust-able chute.

The second preparation process comprises the time from the delivery fromthe chute and the removal of the dust and impurities by means of a fan.By means of the rotating toothed drum, the fodder is already agitatedwith very considerable speed, a speed which is still further increasedby the air suction so that the opened up fodder is kept floating for aninstant and at this moment the particles of dust are quickly releasedand aspirated through the sieve surrounding the fan and driven into theouter air through a delivery pipe.

During the third period of the operation, a shaking up and separating ofthe fodder takes place over the delivery sieve. During this time thereis still aspirated through the fan any dust which has not already beenremoved, whereas other particles fall through the shaking sieve.

By the aid of special scrapers on the shaking sieve the fodder is soaerated and shaken up that the aforesaid advantages are realized to thefull extent. Magnets may be arranged either at the exit from the rotarydrum or on the shaking sieve which will retain any particles of ironwhich may exist in the fodder and by the aid of a nozzle the fodder canhave mixed with it at the delivery point a flavoring liquid of any kind.

A construction of the invent-ion is illustrated in the drawing asfollows:

Figure 1 shows a longitudinal section through the machine. Fig. 2 a halfsection through the machine on the line A-B of Fig. 1. Fig. 3 a halfsection through the machine on the line CD of Fig. 1.

The frame in which the machine is constructed is inclosed with doors andother means of access in such a manner that easy approach can beobtained to all the working parts. Especially the part where the siftingdrum is placed is made easy of access by means of two large doors awhich are closed by the locking handles 6. The supply of the foddertakes place through the hopper c in which there are S-shaped bentrotating rods (Z which facilitate a uniform delivery of the fodder tothe toothed drums. The supply of the hopper 0 can be by means of a liftor the like. Through the hopper 0, the fodder passes to the drum f madeof flat iron rods and provided with teeth 6. These teeth are somewhatsloping and their inclination is opposite to that of the rotation sothat there are no corners in which particles of fodder can remainhanging. Upon the machine frame itself are placed corresponding slopingteeth 9 which with the aid of a worm gear can be adjusted as regardstheir position to the drum f by means of the outer handle it.

The delivery chute 2' is arranged concentrically with the drum andsupported on pivots so that it can be adjusted by means of the slot 7:;and set screws Z at any desired distance from the toothed drum. Uponthis chute i are placed cutters m, and if desired magnets n which arearranged on it in any convenient manner.

Somewhat raised above the toothed drum f there is placed a drum sieve 0close to the door a and this is rotated by means'of a belt and pulley.In this rotating sieve drum is placed the fan 3), the driving axle ofwhich projects through the bearing of the sievedrum 0 and is preferablyrotated in the opposite direction to that of the drum. The sieve drumruns at the side nearest to the fan in a tube 1 through which the dustis taken away to any suitable place. A brush 7" extending over theentire width of the sieve drum is pressed against it by means of aspring 8 and keeps the sieve drum free from particles of fodder duringthe whole operation so that it can act freely.

Over the whole width of the machine un der the toothed drum and sievedrum there extends the sloping screen or sieve t which is moved to andfro and at the same time up and down by means of a crank and pulley w.The screen rests 011 the one hand upon the crank u and is suspended onthe other hand from a hook 00 by the aid of chains 1 preferably so as tobe adjustable in its inclination.

At a suitable point beneath the sieve drum there are placed irons 2attached to a common pivotally supported rod 5, which are thrown up bythe action of the screen t and breaks up the fodder falling upon them sothat even in the most difficult cases in which the fodder is completelyclotted together a thorough breaking up and aerating is effected.

At the outlet point there is a pipe Z ending in a nozzle 2 and connectedwith a receptacle placed at a convenient point for the purpose of addingto the fodder es sences or ingredients which increase its appetizingqualities.

The driving of the machine is effected by means of fast and loosepulleys 8 in the well known manner by a belt and pulley 4 connected tothe toothed drum f. As all the moving parts are driven from the tootheddrum it follows that the speed of them all will be regulated thereby andtherefore the speed of the entire machine can be adjusted according tocircumstances withoutthe possibility of choking or breakage. The drivingof the crank shaft from the toothed drum is effected by the pulley w andthe sieve drum is driven by a pulley on the crank shaft, while the fanis again driven directly from the toothed drum.
